Vehicle emission factors were determined from high time resolution measurements made at a downtown near-road monitoring site in order to better quantify and characterize the impacts of traffic emissions in urban environments. As part of a larger collaborative pilot project with local and federal government agencies, near-road and urban background monitoring sites were deployed in Toronto and Vancouver in order to capture urban-scale air pollution dynamics as a result of anthropogenic activities.

Methane and carbon dioxide fluxes were measured at Haliburton Forest and Wildlife Reserve, a mixed-managed temperate forest in Central Ontario, over a five-month remote field campaign with measurements made at 10 Hz resolution. Eddy covariance method was employed to calculate the fluxes between the atmosphere and ecosystem.

Designed sampling technique for quantitatively analyzing volatile organic compounds in various air samples collected in small canisters, which included smoke from full scale experimental fires conducted at the NRC National Fire Laboratory and from human alveolar breath of smokers and firefighters. Analysis was done using gas chromatography/mass spectrometry (GC/MS). Semi-quantitative method and NIST mass spectral library used to identify chromatographic peaks present in historical database of arson and accelerant samples. Work eventually led to honours thesis project.
